TIRE LIFTING, CARRYING, AND LOWERING DEVICE.

Application filed March 21, 1925. Serial No. 17,205.

My invention has reference more particularly to a tire carrier, wherein a lifting medium is provided to facilitate elevating the tire to the position in which it is carriedon the car.l

Extra tires are usually mounted on a rim or spare wheel and carried in an elevated position on the car. The combined tire and riin or spare wheel is quite heavy and hard to handle and it is not only difficult to lift same `to the elevated position on the car, but inasmuch as the tire is usually dirty the clothes are oftentimes soiled.

The principal objects of my invention are to provide an improved tire carrier; to facilitate the lifting of the tire and rim or spare wheel to the elevated position in which it is carried on the car; to counteract the weight of the tire and rim or spare wheely so that it may be easily raised and lowered; to afford a lifting'tension which is sulhcient to lift automatically the tire and rim or spare wheel to the elevated position; to lock the lifting f mechanism in the elevated position; to utilize a part of the tire carrier as a support in the raising and 'lowering operation; and in general, to afford a simple, compact and convenient tire holder and lifter.

The invention consists in the novel arrangements, constructions and devices to be hereinafter described and claimed for carryingout the above stated objects and such other objects as will appear from the following description of a certain preferred embodiment illustrated in the accompanying drawings, whereinf t Fig. 1 is a side view ofthe rear end of an automobile with my tire carrier and lifter thereon; y

Fig. 2 is a frontview of the carrier and lifter, apart from the car;

Fig. 3 is an enlarged sectional view, partly broken away, taken on the line 3 3 of Fig. 2;

Fig. 4 is a sectional view taken on the line 4-4 of Fig. 3; and n Fig. 5 is a detail View of a lock for holding the lifter in the elevated position.

Lilie characters of reference designate like parts in the several views.

Referring to the drawings, the reference numeral indicates an automobile, at the rear end of which is mounted an upright tube 11 which serves as the casing for the lifting mechanism. This tube may be secured to the car in any convenient manner which will depend somewhat on the rear end construction of the particular car. In the present case a plate 12 is shown, which extends between and cross braces the frame sills 13 and covers the gas tank 14, and I have provided a main bracket 15 which is bolted or otherwise attached to the plate 12 and formed at the outer end with a split clamp 16 wherebythe upright tube 11 is secured thereto. Another clamp 17 is secured to the tube 11 near the upper end and has a pair of divergent braces 17 1 extending forwardly therefrom and bolted or otherwise secured at their forward ends to the plate 12 or other part of the car.

The upper end of the tube 11 is closed by a cap 18, which may be attached to the tube in any suitable manner as by screws 19 arranged at intervals therearound and threaded into the wall of the tube 11. A cap 20 is also attached to the lower end of the tube 11 in any suitable maner as by a threaded connection, as shown, the cap being provided with a large central aperture which is slidably engaged by the tube 21. This tube 21 is sufficiently smaller than the tube 11 to afford an annular chamber therebetween for the compression spring 22 which is seated at the lower end against the cap 20 and at the upper end against an annular flange 23 provided on the upper end of the tube 21. t

A head 24 is secured to the lower end of the tube 21 in any desired manner as by the threaded connection shown, and said head has an opening therethrough, preferably square, to receive the square stem 25 which is suitably locked therein as by the pin 26. This stem has an arcuate trough shaped shoe 27 pivoted on the outer end, which conforms to a portion of the periphery of the tire which is to be carried thereby and serves as the lower holder therefor.

An upper holder of similar shape but inversely positioned is located directly above the lower holder 27 and split longitudinally as at 28 into front and rear sections 29 and 30 respectively, the former of which is rigidly secured to an arm or bracket extension 31 of the cap 18, and the latter of which is hinged as at 32 to the section 29 or the outer end of the-arm 31 so that it can be swung upwardly from the normal position shown in Fig. 3.

lVhen the tire, which is indicated at 33, is in place, the lower portion rests in the holder 27 and the upper portion in the holder 29-30, and is locked in place by the section 30, the latter being held against swinging moveel nvse,

ment by a link or bar which is pivoted at its inner or forward end between pivot lugs 35 on the clamp 17 so as to swing readily through the opening between two spokes into position to have its outer end inserted through an aperture 36 in the section 30 and locked in any convenient manner as by the padlock 3'? which is passed tir ugh an aperture in the projecting end oi the link ln such position, the bar 3d is adapted to support the tire assembly independently ot the spring.

This carrier is designed :tor use with any torni or tire assembly, either Jfor a single tire or a plurality of tires and either olf the ordinary rim or spare wheel of disk, wire or artillery type, a single 4tire carrier oi the latter type being shown herein, and the link 3e is arranged to swing under the upper portion of the rim or wheel and to entend substantially from side to side of the rim or wheel, in the present case under the telly 3S and between the spokes 39. I

lVhen the tire is to be placed in the carrier or removed therefrom, the holder 27 is depressed and the tube 2l slides downwardly in the tube ll, against the tension of the spring Q2, until the head 24 rests on the ground, in which position the tire can be removed from or placed inthe holder 27 by rolling it into the end of the holder or by an easy lift over the side of the holder. Preferably the tubes ll and 2l are cylindrical and the aperture in the member 2O is circular whereby the tube 2l may be turned on its axis and thus permit the tire to be rolled out of the holder 27 without interference from fender, bumpers, or any other projecting parts that may be present on the car. rlhe spring?J may be of any desired tension, that is, to counteract more or less ot the weight of the tire and rim or spare wheel and permit same to be easily litted tothe carrying position, but l prefer to use a spring which has suicient tension to lift automatically the tire and rim or spare wheel to the carrying position without any eort ot the person whatever, except to stead?.7 the tire and directit into the opened. up holder 29-30.

Gbviously, with a spring orp such tension it is desirable to hold the parts in the lowered position against the lifting tendency of the spring, and for this purposethe tube 2l is internally formed at the upper end with a series ot rack teeth l0 and a long pawl il is pivoted its upper end between pivot lugs 4Q on the cap 18 and has a pointed toe at its lower end for engagement with the rack teeth il() when the tube 2l is depressed. e leal2 spring lined to the wall of the tube 2l bears against the back ci the pai-.vl to force the pointed toe 43 into engagement with the teeth 40, and an integral arm l5 entends laterally from the upper end orn the pawl ell through, a vertical slot i6 in the wall of the tube ll so that the operator may conveniently release the pawl Lll.

2l preferably has just sullicient positively litt the tire to the carryposition in order that the tire may be ily pressed down to the ground, and it is desirable, in order to prevent chattering when the car is running, to lock the tube 2l securely in the uppermost position. To this end l have provided an automatic lock, controlled by the link Bil. Said lock comprises a bar l? which is pivoted at its lower end to the link Se and is iormed with a bend at the upper end adapted to project through a slot i8 in the wall ot the tube ll, said bar a7 havin@- a pointed end which engages a recess or seat el) in a lug or extension on the upper end of the tul 2l. A.. strap 5l on the tube 2l holds the upper end of the bar d'7 against displacement and the angularity of the upper d ot the bar e?? is such that when the link 3l is swung downwardly the upper end of the bar is Yfully with 1rawn from the seat 49 and when the link 34 is raised to the locking position the strap 5l directs the upper pointed end ot the bar e? into engagement with the seat lliththis arrangement the locking of the tube 2l in the elevated position is not only positively insured when the link Sil is swung up to loc t the tire in the carrier, but tl nere is sufficient lifting leverage on the bar 4:7 to insure a clamping ot the tube 2l in the elevated position and hence a rigidity that will prevent chattering.

l do not intend to limit my invention to the details of construction shown and described, except only in so :tar as certain oi the appended cla'ms are speciiically so limited, as it will be obvious that modilications may be made without departing from the principles ot' my invention.
